Description

Lignin CAS NO 9005-53-2 is a complex, cross-linked aromatic biopolymer that serves as a key structural component in plant cell walls. This renewable and abundant natural resource is gaining significant commercial importance as a sustainable alternative to petroleum-based materials. It is essential for industries seeking bio-based binders, dispersants, and performance additives to enhance product sustainability and functionality.

Application

• Concrete Admixtures & Dispersants: Acts as a water-reducing agent and plasticizer to improve the workability and strength of concrete.
• Animal Feed Pellet Binder: Used as a natural binder to improve the durability and reduce dust in feed pellets.
• Dust Control Agent: Applied for soil stabilization and dust suppression on roads and construction sites.
• Agricultural Applications: Functions as a carrier for pesticides, fertilizers, and as a soil conditioner.
• Vanillin Production: Serves as a primary raw material for the industrial synthesis of natural vanillin flavoring.
• Carbon Black & Rubber Reinforcement: Used as a reinforcing agent and processing aid in rubber compounds and carbon black dispersion.
• Foundry Sand Binder: Acts as an eco-friendly binding agent for sand molds in metal casting.
• Polymer & Composite Materials: Incorporated as a filler or modifier to enhance the properties and bio-content of plastics and composites.

Quality Control

Our Lignin products undergo rigorous quality testing to ensure batch-to-batch consistency and compliance with industry standards. We offer various grades tailored to specific applications, with key parameters including sulfonate content, purity, molecular weight distribution, and ash content. Certificates of Analysis (COA) detailing these specifications are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); keep the container tightly sealed when not in use to prevent moisture absorption and caking.
